Now that he is an established potentate of American theater, David Mamet has had no trouble saying what he really thinks. Jews may remember his 2002 essay in The Forward, where he lambasted Jews for over-sympathizing with Palestinians. They will probably remember better his 2006 book, "The Wicked Son: Anti-Semitism, Jewish Self-Hatred and the Jews," where he took it further, arguing that liberal Jewish antagonism toward Israel was simple self-hate.
